Creating Functional Components
In React, functional components are functions that return JSX. They are simpler and more modern compared to class components.
Synopsis:
Functional components are the simplest way to define components in React. They are ideal for components that don't need to manage their own state or directly access lifecycle methods.
- 1. Define the function:
Use the keyword
constorfunctionto define a component. - 2. Return JSX:
The function must return a tree of JSX elements that represents the user interface.
- 3. Export:
Export your component to use it in other parts of your application.
Purpose:
- Provide a simple and efficient way to define components in React using functions.
- Facilitate the creation of reusable components with less code and a clearer syntax.
- Allow the use of hooks to intuitively manage states and side effects.
- Improve performance and code readability in modern React applications.
